Recently, we have published the manuscript entitled “Comparison of intravascular ultrasound versus angiography-guided drug-eluting stent (DES) implantation: a meta-analysis of one randomised trial and ten observational studies involving 19,619 patients”. Two additional important studies (namely, the ADAPT-DES and the RESET), comparing IVUS- and angiography-guided DES implantation have recently been reported1,2. In addition, the two-year clinical follow-up of the randomised AVIO trial was published recently3. Therefore, our meta-analysis needs to be updated.
